What is the cheapest Medicare plan on a fixed income?
Short answer
There is no single "cheapest plan" — the lowest-cost setup is usually a cost-assistance program you qualify for, not a plan you shop for. A $0-premium Medicare Advantage plan looks cheapest on paper, but a Medicare Savings Program or Extra Help can eliminate premiums, deductibles and copays entirely for people who qualify, on top of whatever plan you already have.
Four programs do the actual work: Medicare Savings Programs (state-run, pay your Part B premium and sometimes your cost-sharing), Extra Help (federal, pays most of your Part D drug costs), dual eligibility for Medicaid (the strongest combination, for the lowest-income beneficiaries), and PACE (for people who need nursing-home-level care but want to stay at home). Most people who ask this question qualify for at least one and have never applied.
Income and asset limits are set by your state and adjusted most years, so this page describes how the programs work rather than quoting figures that may already be out of date. A licensed agent or your state Medicaid office can check your specific numbers against the current limits.
The four programs, side by side
| Program | What it pays for | Roughly who qualifies |
|---|---|---|
| Medicare Savings Program — QMB tier | Your Part B premium, and your Part A/B deductibles, coinsurance and copays. The strongest of the three MSP tiers. | Lowest income of the three tiers, roughly at the federal poverty level, with an asset limit. |
| Medicare Savings Program — SLMB / QI tiers | Your Part B premium only. | Somewhat higher income than QMB, still low, with an asset limit. |
| Extra Help (Part D Low-Income Subsidy) | Most or all of your Part D premium, deductible and drug copays, and removes the coverage gap. | Low income and modest assets. Since a 2024 federal change, everyone who qualifies gets the full subsidy — the old reduced/partial tier no longer exists. |
| Full Medicaid (dual eligible) | Effectively all remaining Medicare cost-sharing, plus benefits Medicare does not cover at all, such as long-term care. | Meets your state's Medicaid income and asset test, which is generally lower than the MSP limits. |
Why "$0 premium" is not the same question
Many Medicare Advantage plans advertise a $0 monthly premium, and for someone comparing plan brochures that looks like the cheapest option. It is not the same thing as the programs above, for two reasons.
- A $0 plan premium still leaves your Part B premium, plus copays and coinsurance, whenever you use care. None of that is eliminated by the plan being $0; it only means the plan itself does not add a further charge on top.
- The programs above can apply no matter which type of coverage you choose. A Medicare Savings Program pays your Part B premium whether you are in Original Medicare or a Medicare Advantage plan. Extra Help lowers your drug costs whether your drug coverage comes from a stand-alone Part D plan or an Advantage plan that includes one. Qualifying for assistance is usually worth more than switching plans.
For people who do not qualify for any assistance program, a $0-premium Advantage plan is often genuinely the lowest monthly outlay — see our Advantage vs Original Medicare comparison for the trade-off between low premiums and predictable costs.
How to find out if you qualify
- Do not assume you earn too much. Limits are higher than most people expect, count income differently than tax returns do, and are reviewed every year. Applying costs nothing and does not affect your Medicare coverage either way.
- Apply for the Medicare Savings Program through your state Medicaid office, not through Medicare or Social Security directly — MSPs are state-administered even though they pay a federal premium.
- Apply for Extra Help through the Social Security Administration, at ssa.gov or by phone, unless you are already approved for an MSP or Medicaid, in which case it happens automatically.
- If you need help at home with daily activities, ask your state Medicaid office about PACE (Program of All-Inclusive Care for the Elderly) — it is only available in some areas and combines Medicare, Medicaid and long-term-care support into one coordinated program.
- Ask a licensed agent to run the comparison both ways, with and without assistance, before you enroll in or change any plan. The right plan can look different once assistance is factored in.
Frequently asked questions
What is the cheapest Medicare plan on a fixed income?
For most people the biggest saving does not come from picking a specific plan — it comes from qualifying for a Medicare Savings Program, Extra Help, or full Medicaid, any of which can be combined with the plan you already have. A $0-premium Medicare Advantage plan is usually the cheapest option only for people who do not qualify for any assistance program.
How much does Medicare cost per month for someone with a low income?
It depends entirely on which assistance programs you qualify for. Someone approved for the QMB level of a Medicare Savings Program can have their Part B premium and most cost-sharing covered, leaving very little out of pocket. Exact figures vary by state and by year, so check your current numbers with your state Medicaid office.
Do I need to apply separately for Extra Help and a Medicare Savings Program?
No. If you are approved for a Medicare Savings Program, you are automatically enrolled in the full Extra Help subsidy for Part D. You can also apply for Extra Help on its own through Social Security if you do not qualify for a Medicare Savings Program.
Does a Medicare Savings Program work with Medicare Advantage, or only Original Medicare?
Both. A Medicare Savings Program pays your Part B premium and, at the QMB level, your cost-sharing, regardless of whether you are enrolled in Original Medicare or a Medicare Advantage plan.
What is PACE and how is it different from a Medicare Savings Program?
PACE (Program of All-Inclusive Care for the Elderly) is a combined Medicare and Medicaid program for people who need a nursing-home level of care but want to keep living at home. It provides comprehensive medical and support services through one coordinated team, rather than paying a premium or cost-sharing on your existing plan. It is only available in areas where a local PACE organization operates.
Will applying for assistance affect my current Medicare coverage?
No. Medicare Savings Programs, Extra Help and Medicaid work alongside your existing Medicare coverage, whether that is Original Medicare or a Medicare Advantage plan. Applying does not put your Medicare enrollment at risk, and you keep your Medicare either way regardless of the outcome.
